Turned out to be the 45 watt version, and it was in even better condition than I hoped. The tolex and grill look 100% mint, and the faceplate is probably at about 95% mint.
I absolutely love the sound of this thing. I didn't think I would notice that much of a difference, but I definitely like it a lot more than the Twin reissue. Plus, having the master volume is much nicer than having to deal with the Power Soak.
